Description

[Detailed Description of the Invention] The present invention relates to the structure of a pressure regulating valve in a pressure cooker.

As a pressure regulating valve used in conventional pressure cookers,
The base end of a valve hole body with a locking seat in a pressure regulating valve of a pressure cooker, which is attached to a lid body that is attached to a container and is equipped with a pressure regulating valve that releases steam when a predetermined steam pressure is reached during boiling. In the pressure regulating valve, the protruding part of the proximal end is fixed to the back side of the lid body by passing the part through the lid body, and the lower end of the valve hole body has a
There were shielding caps with a number of holes drilled in them that were screwed on, or screwed caps with steam holes on the lower end of the valve hole body to fix the valve hole body.

However, the steam vents for the above-mentioned shielding caps and caps that fall down are small and have multiple holes, so if you use a pressure cooker frequently, you will not be able to do fine cooking. Occasionally, the steam vents become clogged and the valve is used without noticing, resulting in unreliable valve action, which is extremely dangerous, and also causes clogging of the large number of small steam vents. When this occurs, in order to clear the clogging, each hole must be inspected and the slag clogged in the holes must be removed, which is extremely time-consuming and inconvenient for use.

Recently, a pressure regulating valve has been devised in which a part of the valve seat protrudes from the through hole of the lid body into the container, and this protruding part is provided with a plurality of grooves communicating with the steam communication port. In this type of valve, the lower part of the valve seat of the pressure regulating valve is specially machined to provide the above-mentioned protrusion, which is inconvenient and costly, and also causes deformation if other objects get caught on the protrusion. This causes a decrease in safety due to blockage of the kerf, etc. Also, when clogging occurs, the valve cannot be easily removed, making it inconvenient to remove the clogging. It was also incompatible.

The present invention is a pressure cooker in which a filter body that also serves as a connecting member for the valve hole body is screwed onto the protrusion at the proximal end of a valve hole body that penetrates the lid body of a pressure cooker, and the filter body corresponds to the lower end of the valve hole body. A safe pressure cooker that has a communication port consisting of multiple grooves in the section to prevent clogging of the valve hole, and also allows for reliable installation of the valve hole body and easy attachment and detachment of the valve hole body. The present invention relates to a pressure regulating valve in the industry, and an embodiment thereof will be described below with reference to the drawings.

When the load body 13 is lifted by the steam pressure, the valve hole 11 of the valve hole body 10 is opened.
Open it and let it air out.

Reference numeral 15 denotes a filter body which also serves as a connecting member for the valve hole body 10 screwed onto the base end 16 of the valve hole body 10, and has a bottom portion 17 having a wall thickness similar to that of the screwing peripheral wall and a thin bottom portion. Using a hexagonal nut, screw the valve hole body 10 that passes through the lid body 3 into a male screw 18 carved in the proximal end 16 of the protrusion on the back side of the lid body 3. It is fixed to the lid body 2 and covers the base end 16 of the valve hole body 10.

Reference numeral 19 denotes a communication port provided in a portion corresponding to the lower end of the valve hole body 10 in the filter body 15, and a plurality of grooves 20 extending from the thin bottom portion 17 to the threaded portion of the threaded peripheral wall are formed in a radial or parallel manner.
A center hole 21 is provided in the center in a crisscross shape and having the same center as the valve hole 11.

A banking 22 is interposed between the locking seat 9 of the valve hole body 10 and the lid main body 3, and prevents leakage of steam from the insertion hole 23 of the valve hole body 10 formed in the lid main body 3.

Reference numeral 24 denotes an airtight member interposed between the lid main body 3 and the filter body 15.

Reference numeral 25 designates another pressure regulating valve provided on the lid body 2, in which a valve 28 and a spring 29 are housed inside a valve hole body 27 with a locking seat 26 attached to the lid main body 3; A screw lid 31 for adjusting the elasticity of the spring 29 is screwed onto the upper end of the opening 30 of the valve hole body 27 so that the steam pressure can be adjusted to at least 2.3 atmospheres during boiling. A filter body 33 having the same structure as described above is screwed onto the base end 32 protruding from the back side of the filter body.

A is a pressure cooker consisting of a container 1 and a lid 2, in which both ends of the lifting rod 6 of the lid 2 are loosely locked to hook-shaped holders 34, 34 provided on both the left and right sides of the container 1, and the The lid body 2 is pressed onto the container 1 by rotating and tightening the pressure knob 5.

Reference numerals 35 and 35 denote handles attached to the left and right sides of the peripheral wall of the container 1 together with the receiving parts 34 and 34.

The filter body 15 in the present invention is shown in FIGS. 3 to 6.
As shown in the figure, there are cases in which a plurality of kerf grooves 20 intersect, or a plurality of horizontal kerf grooves 20 are provided with vertical side kerf grooves 20.

Since the pressure regulating valve in the pressure cooker according to the present invention is constructed as described above, for example, when attaching a weight-type pressure regulating valve to the lid body 2, first insert the valve hole in the appropriate position on the top surface of the lid body 3. Raise the insertion hole 23 of the body 10, insert the base end 16 of the valve hole body 10 into the insertion hole 23, and insert the locking seat 9 formed on the valve hole body 10 into the upper hole end of the insertion hole 23. After being supported,
The filter body 15 is screwed onto the male thread 18 of the base end 16 protruding from the back side of the lid main body 3, and this is tightened, and the filter body 15 is screwed and the locking seat 9 is locked. Valve hole body 10

In addition, in the case of another pressure regulating valve 25 that adjusts the elasticity of the spring 29 to a predetermined pressure, the valve hole body 27 is inserted into the insertion hole drilled in the lid main body 3, and then the lid main body 3 is inserted. After attaching the valve hole body 2T by screwing the filter body 33 to the base end 32 protruding from the back side of the valve body 3, the valve hole body 2T and the spring 29 are accommodated, and then the upper end of the valve hole body 27 is attached. A screw lid 31 is screwed onto the lid 31 and rotated to adjust the elasticity of the spring 29 so that it can withstand a predetermined steam pressure.The filter body 33 in this case also has a communication hole at the bottom. This prevents the valve hole body 27 from clogging.

As mentioned above, the pressure regulating valve in the pressure cooker according to the present invention is attached to the lid that is attached to the upper opening of the container.
The base end of the valve hole body with a locking seat in the pressure regulating valve of a pressure cooker equipped with a pressure regulating valve that releases steam when a predetermined steam pressure is reached penetrates the lid body and is attached to the back side of the lid body. In a pressure regulating valve of a pressure cooker that protrudes from the bottom and fixes a protrusion at the base end, the valve hole body is fixed to the lid by screwing into the protrusion, and the base end of the valve hole body is fixed to the lid body. A filter body that also serves as a coupling member for covering is screwed together, and the filter body has a thick peripheral wall and a thin bottom part, and is screwed into a part corresponding to the lower end of the valve hole body from the thin bottom part. Since the communication port is formed with a plurality of grooves that reach the threaded portion of the peripheral wall, the base end of the valve hole body is long enough to allow the filter body to be screwed into it, and is covered by the filter body. Even when washing the lid, you will not get your fingertips caught on the valve hole body and get injured, and since the filter body also serves as a connecting member for the valve hole body, the attachment of the filter body will prevent the valve hole body from sticking. can be done at the same time, so
The installation process can be done smoothly and quickly, and since no special accessories are required for attaching the filter body, it can be manufactured at low cost.Furthermore, the filter body has multiple grooves. A communication port is provided, and even if this communication port becomes partially clogged, since the ventilation section is groove-shaped, there is no risk of affecting the air released, and the present invention is different from the conventional one. Unlike the case where the protruding part of the valve that protrudes into the container has multiple grooves that communicate with the steam communication port, the valve hole body is cut into a filter body that also serves as a connecting member for fixing the valve hole body to the lid body. The filter body has a thick wall and a thin bottom wall, and the cut groove extends from the bottom to the threaded part of the wall. It is compatible, does not require high processing costs, and even if other objects get caught during use, there is no risk of deformation and clogging of the cut groove, and there is no risk of clogging. Even if the cooking device gets stuck in the groove, the slag can be easily removed from the groove end, so the pressure regulating valve always functions reliably, and water droplets can be smoothly discharged by steam. Because it can be done reliably, it has the unique effect of greatly increasing safety.
